Fraction Multiplication - Area Model

In this picture, the grey rectangle represents one unit of area. Two fractions can be shown relative to that rectangle, as well as their product.

Can you see how the sketch shows the red fraction? The blue fraction?

If you uncheck show product, can you predict what it will be?

Can you see why the unsimplified product is what it is?

Does the simplified product make sense compared to the grey rectangle = 1?
